Might be a pretty sought after mushroom for eating: https://en.wikipedia.org/wiki/Leucopaxillus_giganteus An identification tool like MatchMaker can be used to help figure it out. By the way, you can pick it. You can't get hurt from touching any mushroom. You can even taste mushrooms in your mouth (experts do this then spit them out). Digestion is when you get hurt from eating the wrong mushroom. If you picked it, took more photos from different angles and did a spore print we could pin it down. A spore print is when you set it on a piece of printer paper overnight. In the morning you'll have a pattern of spores on the paper. The color of the spores greatly helps with identification. Europeans used to be avid mushroom hunters and would add them to meals all the time. Unfortunately the USA has a significant case of Mycophobia. It just wasn't something handed down through generations unfortunetly.
